Day 172 of the 365 to 40 project. Some small and extremely well beaten up spherical magnets. You can’t really buy these in Australia anymore as they can be extremely hazardous for kids and pets, if they swallow them they can clip bits of gut together and cause serious issues. If you do have some in your house do be careful with them. These ones are handy because the spheres are the exact right size to fit in LEGO minifigs leg stud ports to make them stick to metal surfaces.
